What confuses me is the status indicating no deleted files:

                  Account ID: 00000555
              Last object ID: 42934
                 Blocks used: 2806701 (10963.68Mb)
    Blocks used by old files: 265 (1.04Mb)
Blocks used by deleted files: 0 (0.00Mb)
  Blocks used by directories: 5055 (19.75Mb)
            Block soft limit: 3145728 (12288.00Mb)
            Block hard limit: 3407872 (13312.00Mb)
         Client store marker: 1132633067000000

A good 6Gigs or more here are consumed by the mpeg files.  I don't know 
the internals, but I can easily imagine how these files may remain stuck 
there forever since they have made it to the backup legitimately and 
have never been deleted, just filtered out. 

Separately from that, I agree the use of REs causes more confusion and 
uncertainty than the additional power vs good old wild card is worth 
it.   But I do not want to complain too much.  This is easily the best 
modern backup I can find, so I am hoping for the best and counting on 
continual evolution toward better usability.
